I've update from 3.0.12 to 3.0.14Please describe your problem. My forum was frozen for a very long time. Only in this days I'm return to work on it.
First I've update to 3.0.14 (no problem during the update) and no problem with the board from pc.
Later I try to access to forum from my smartphone (android) and I can't login. If I click login I login successfully, but on the next page the forum ask me another time to login.
From smartphone I can't manage my board because I can't login to the control panel, I can't post or read and I can't access to my control panel.
I'm in trouble because I don't use my forum for a long time so I don't know if the problem is about my board or is a problem of phpbb on mobile deviceGenerated by SRT Generator

It seems like your style is slightly outdated. I can't instantly say if that's the root of your problems or not, but you could try temporarily enabling the default 3.0.14 blue prosilver style and see if that resolves the problem. If it does, then you need to update your ColorizeIt style to the latest version.
